This exhibit depicts the coronal pre-op and post-op conditions of the ethmoid sinuses and orbital structures. Pre-operatively, the ethmoid sinuses are seen without evidence of disease. A wrongful diagnosis of acute sinusitis was made, leading to unnecessary ethmoid sinus removal surgery. During the procedure, the medial wall of the right orbit was fractured, transecting the right medial rectus muscle of the eye, and injuring the inferior rectus muscle. Resulting post-operative deficits include outward drifting of the right eye due to muscle damage, and fluid buildup within the ethmoid sinuses secondary to orbital wall fractures.
